PATENT J. SEVRANCE STEWART, OF HOMER, NEW YORK.

Specification forming part of Letters Patent No. 52,767, dated February 20, 1866.

To all whom it may concern:

Beit known that I, J. SEVERANCE STEW- ART, of Homer, in the county of Cortland and State of New York, have invented certain new and useful Improvementsin Ghurns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

In the annexed drawings making part of this specification, A represents abarrel or round churn, which is placed on a circular disk or base, B. From the base B, and extending up on both sides or two sides of the churn, are two uprights. one of which is seenv in dotted line and marked C. To one ofthese uprights, at its top, ishinged a bar, P, which lies across and above the churn and fastens, by means of a pin orother convenient method, to the other upright at the end opposite the one which is hinged.

L represents a shaft., which lies crosswise of the bar l, and has its journal-bearings upon said bar. The shaft L is provided with two bevel-gear wheels, J and K, as shown in the ligure. The shaft Lis formed in the shape of a crank between the two bevel-gear wheels J and K, and a small pitlnan, M, is connected to this crank. To the bottom or lower end of the pitman M is secured a disk with a valve in it. This disk works and fits in a tube, D, and is for the purpose of forcing air into the churn, as will be described.

G represents a bar, which slides down on the inside of the churn, and against its sides, to which bar is attached a series of stationary7 dashers, F F. I may use one or more of these bars with stationary dashers.

D represents a metallic tube, which is surrounded with a sleeve of wood, (marked N,) and which is placed in the center of the churn, running from top to bottom. To the wooden sleeve are secured the dashers E E.

In the bottom of the churn is secured a conical pin, c, which fits into an opening in the lower end of the sleeve N, and upon the base B is a similar pin, which ts into an opening in the bottoni of the churn. The flasher-staff, composed of t-he tnbeD and sleeve N, revolves upon one of these pins, and the churn revolves upon the other.

O represents the top of the churn, and secured at the center and. upon this top is a bevel-gear wheel, H, into which meshes this gear-wheel J upon the shaft L. By means of these wheels and the shaft L the churn is made to revolve.

I represents a bevel-gear wheel, which is secured to the upper end of the tube-D and lies immediately over the gear-wheel H. This wheel I meshes into the wheel K on shaft L, and byv this means the dashers upon the sleeve N are made to revolve, all being secured to the tube D.

In operating this machine the shaft L is revolved by means of a crank-handle, R, upon it. This revolves the wheels K and J, and they revolve the churn and the dasher-shaft within in different directions. At the same time the pitmanfM is worked up and down, and air being forced into the churn escapes into the cream through the holes w x, in the lower part ot' the tube D.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The arrangement ofthe shaft L, wheels K and J and VI and H, pitman M with the ,tube D, and revolving churn provided with dashers, the several parts being constructed and used as and for the purpose herein set forth.

In witness that I claim the foregoing, I have hereunto set my hand in the presence of two witnesses.
